Abstract
Proximal row carpectomy (PRC) is a motion preserving surgical procedure utilized to treat degenerative conditions of the wrist.Although it is generally considered a salvage procedure and considerably alters wrist biomechanics, it has been shown to reliably reduce pain and improve function.PRC is a resection of the proximal carpal row and includes the triquetrum, lunate, and scaphoid bones, allowing the capitate to articulate with the lunate facet of the distal radius. The removal of pain producing articular surfaces and creation of the new radiocapitate articulation maintains wrist motion and can relieve pain. Excision of the proximal carpal row has proven over the past 60 years to be an effective technique for certain disorders of the wrist , including degenerative sequelae of scapholunate ligament dissociation and scaphoid nonunion , Kienböck’s disease, Preisser disease, and other fracture- dislocations of the wrist.The durability of this procedure may be due to remodeling of the capitate head to the lunate fossa.Preservation of relatively normal cartilage of the capitate head as well as the lunate fossa is critical for success of this procedure
